generator running but no power checked breaker, all seems fine but no power?
it is a 8500 watt briggs and straton has 224 hrs was working fine then no pwer starts up fime
Assuming there are no problems with the circuit breaker or loose wiring, you may have to flash the generator field. Two things to try:
1. Shut off the engine and remove any cords from the generator. Plug in a cord with bare wires on the other end to one of the 120VAC outlets. Connect one end of the cord to a car battery. Very quickly touch the other wire to the other battery terminal. Do not leave it there longer than to create a few sparks or you may destroy the windings. If the residual magnetism in the alternator had weakened, this may be enough to get it started again.
2. This tip comes from the Briggs & Stratton Customer Education Department via Precise Engine Repair web site. http://www.perr.com/
As an alternative to flashing a rotor winding with a battery applied to the brushes, an electric drill may be used. Follow these steps to flash the generator:
Plug the electric drill into the generator receptacle.
If the drill is reversible, move the direction switch to the forward position.
Start the engine.
While depressing the trigger on the drill, spin the drill chuck in reverse direction. This will excite the field and the generator will now produce electricity. If spinning the chuck one direction does not work, try spinning the chuck in the other direction as you may have the reverse switch positioned backwards.
Use caution not to get your hand or other materials caught in the chuck. As soon as the field is excited, the generator will produce power and the drill will turn on.
The reason this works is because the electric motor in the drill will act as a small generator when spun backwards. The magnets in the drill's motor induce a voltage into the motor windings, which is fed back through the trigger, cord and into the generators receptacle. From there it goes into the power winding of the stator. The voltage going through the power winding creates a magnetic field, which is intensified due to the iron core of the stator laminations. The rotor intersects this magnetic field as it is spun past the power winding, thus inducing a voltage in the rotor winding. Once current flow is present in the rotor winding the rotor has been flashed.
